I bought the KP3+ second hand and sold it probably a year later still in great condition
I didn’t like the effects that much it was way too digital for me and I was getting better FX from inside my DAW. If I was playing live at the time it would o been a keeper as it had plenty of FX at a great price
In my opinion the best thing about the Korg Kaoss Pad KP3+ is not the effects it’s the looper. It was easy to operate and you could record 4 loops on the go. You could resample those loops to “bake ” the FX within those loops.
You could also record loops onto the sd card and be able to load those loops up again.
Coming from looping into Ableton and having mess around with turning the computer on and setting up the correct audio channels etc was a pain for me. The Kp3 was awesome plugin and play.
